I saw this when it was at Radio City and have spent a bit of time listening to the recording today.
Rachel is undoubtedly an incredible vocalist, she sings with such ease and power, but I personally find there to be a lack of emotion in her performances of these songs. She is young and I think needs a director to really pull something out of her. Still, a treat to hear her sing this music.
Platt I was doubtful of when he was announced, but I found his take on Jamie to be very unique and true to him. Thought he embodied the role very well and loved his take on Schmuel Song.
Always nice to get to hear this music sung so well!
